Deception and appalling greed in male (11)
I believe the answer is:
legerdemain
'deception' is the definition.
(I know that deception can be written as legerdemain)
'appalling greed in male' is the wordplay.
'appalling' indicates anagramming the letters (an appalling spelling).
'greed'+'in'+'male'='greedinmale'
'greedinmale' with letters rearranged gives 'LEGERDEMAIN'.
'and' acts as a link.
(Other definitions for legerdemain that I've seen before include "Find the lady will require this skill" , "sleight-of-hand" , "Magician's skill" , "Sleight of hand" , "leads to deception" .)
